John Couch Adams was an English mathematician and astronomer, born on June 5, 1819. He is best known for his role in the discovery of the planet Neptune. Adams used mathematical calculations to predict the existence and position of Neptune based on irregularities in the orbit of Uranus. In 1846, his predictions were confirmed when Neptune was observed by astronomers. Adams's work not only advanced the field of astronomy but also showcased the importance of mathematics in understanding celestial bodies. He later became a professor at Cambridge University and contributed to various scientific fields throughout his career.
